Title: Alarming device for vehicle
Inventor: SUZUKI TATSUYA
IPC: B60T7/12
Filed: 2002-11-12
Abstract: <P>PROBLEM TO BE SOLVED: To sufficiently display the function as an alarm for a contact possibility without making a driver feel troublesome.  <P>SOLUTION: When an own vehicle is running on an ascending road (step S22), a threshold value and a control gain which become parameters for the alarm for a contact possibility are made smaller in response to the gradient of the ascending road (step S22).

The threshold value specifies the alarming timing of the alarm for the contact possibility, and the control gain specifies the strength of the alarm (braking force). Therefore, when the own vehicle is running on the ascending road, for the alarm for the contact possibility, the alarming timing becomes later, and the strength becomes weaker. In the meantime, when the own vehicle is running on the descending road, for the alarm for the contact possibility, the alarming timing becomes earlier, and the strength becomes stronger.  <P>COPYRIGHT: (C)2004,JPO
